TUBING FOR 'WIND INSTRUMENTS.

Specification of Letters Patent.

Patented Aug. 30, 1910.

To all whom it may concern.'

Beit known that I, MERVIN M. RUBRIGHT, a citizen of the United States, residing at IIartville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Tubing for Wind Instruments, of which the following is a speciication.

The object of my invention is to produce a casing for wind instruments that will maintain its original shape and not be cracked by reason of seasoning or climatic changes; with this and minor objects in view, my invention consists of the parts Vand combination of parts as will be more fully hereinafter set forth.

In the drawing, Figure 1 is a side elevation of a clarinet embodying my invent-ion; Fig. 2 is a longitudinal section of the same; Fig. 3 is a longitudinal section of the joint showing the members disjointed, parts being in elevation; Fig. 4 is a section on the line 4.-4, Fig. 1, and Fig. 5 is a vertical sectional view of a slightly modified form.

While I have, for the purposes of illustrating my invention, shown it as applied to a clarinet, it will be understood that the use of the invention is not restrict-ed to clarinets, as it may, with equal facility, be employed in the manufacture of other musical wind instruments.

l represents a metallic shell or base, which is preferably formed of brass or aluminum, of suicient strength to give the necessary rigidity to the instrument, whether it be a clarinet, flute, fife or any other rigid wind instrument. This base may be formed in any convenient manner, either by molding or formed upon mandi-els or possibly by the use of suitable dies. The inner and outer faces of the base are roughened in any suitable manner for the purpose as hereinafter set forth, of better forming a close union between the metallic base and the outer shell of the instrument; and also between the metallic base and the inner lining of the instrument.

Upon the outer surface of the metallic base l is vulcanized a shell or outer casing 2, which shell is preferably formed of rubber. The lining 3, which is preferably of rubber, is vulcanized on the inner face of the base 1. While I have described the lining and outer casing of the instrument as being of rubber, I do not desire to be confined to the use of rubber, as it is well understood that any material having the qualities of hard vulcanized rubber may be substituted.

As will be seen more clearly in Fig. 3, one end of the sections is tapered as at fl, on which is secured a soft rubber band or covering 5 which produces a yielding eect and thereby a close air-tight joint. The opposite end of the section is provided with a tapering socket 6 adapted to receive the tapering end of the adjacent section. It will be noticed that the base l does not extend the full length of the section, but terminates at the base of the tapering socket.

IIeretofore instruments of this kind have been formed from a class of wood having fine and close grain, such as ebony, but great difficulty is experienced by reason of the sections of the instruments becoming warped or cracked to such an extent that the instrument becomes practically worthless.

By first forming a metal base of proper diameter upon which the outer casing and vt-he inner lining of the instrument are formed, the original shape and contour of the instrument is maintained under all circumstances by iixedly attaching the lining and the outer casing or shell to the base, I am enabled to produce an instrument that will maintain its original shape and not become cracked from seasoning or from any other cause when the instrument is used in the ordinary manner.

As is well known to those skilled in this art, musical instruments of this kind are formed in any suitable number of sections, joined in such a manner that air will not escape at the joints. The joints between the sections, are formed by continuing thev outer casing or shell of each section beyond the base l a 'distance equal to the length of the lap of the sections, in order to make the inner periphery of the extended or lapped portion 4 of the same material as the outer shell, which is vulcanized to the base l. The inserted portions of the various sections are, of course, formed of such a diameter that they can be inserted and properly connected, and, for strength, the metallic tube or base l` is preferably extended to form a base or support for the tapered end 4L of the various sections,

It will be understood that apertures should be formed in the metallic base, the

casing and the lining, and the keys (not shown) attached in any convenient and Well known manner.

If desired, I may use the metallic shell or base as the lining of the instrument and thus omit the use of the vulcanized lining, in Which case the inner face of the lining should be smooth, as shown in Fig. 5.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:-

1. In a musical Wind instrument composed of sections, the combination with a metallic base, of a vulcanized outer covering extending beyond one end of said base to form a socket to receive the end of an adjacent section, and the tapered end of an adj acent section provided With the metallic base out to the extremity thereof and adapted to lit said socket in such manner as to bring the bases of the sections into engagement with each other.

2. A musical Wind instrument comprising a plurality of sections, each section comprisingvar. metallic base, a vulcanized outer covering extending beyond one end of the base to form a socket, While the other end of said covering is tapered, a soft rubber band on the tapered end, and a vulcanized inner lining on said base.

3. A wind musical instrument comprising sect-ions, each section having a tube of rigid material to maintain the shape of the instrument, tubular layers of hardened plastic material applied and permanently secured to the outer and inner faces of the tube of rigid material, the outer layer thereof extending beyond the tube of rigid material and forming a socket to receive the end of the adjacent section.

The foregoing specification signed at Hartville, Ohio this first day of October, 1907.
